Editing Interaction examples

{{av}}

This page was created to aid those curious about the interaction process by providing example interactions for them to use or study. Those familiar with interaction raws should feel free to add helpful/obscure information to the lists below to help members of the community less experienced with interactions.

==General Tips==

===Synchronizing Adventure and Fort Mode syndrome timers===
Fort mode runs 72 times faster than Adventure mode - which means that a syndrome that lasts a single tick in Fort Mode will last 72 ticks in Adventure Mode.  For short-term syndromes, this will cause very different behaviors between the two modes.  In order to ensure that a syndrome operates the same way regardless of mode, add DWF_STRETCH:72 to the end of the CE effect tag.

It is not possible to make a syndrome that lasts shorter than 72 ticks in Adventure Mode.

===Syndromes with no effect===
There are times you will want to create a syndrome that has no actual effect - generally in order to add a SYN_CLASS that renders the target untargetable by a different interaction.  Syndromes disappear once their effects have expired, so to do this you will need to add an effect that does nothing.
Some examples:
{{gamedata|title=Useless syndrome tags|
[CE_SPEED_CHANGE:SPEED_PERC:100:START:0:END:1:DWF_STRETCH:72] <-- Makes the target move at 100% of its current speed

[CE_SKILL_ROLL_ADJUST:PERC:100:PERC_ON:0:START:0:END:1:DWF_STRETCH:72] <-- Multiplies the target's skill by 100%, 0% of the time

[CE_MATERIAL_FORCE_MULTIPLIER:PROB:100:MAT_MULT:NONE:NONE:1:1:START:0:END:1:DWF_STRETCH:72] <-- Makes the target take 1/1 times its normal damage from attacks
}}

So if you see tags like this in the examples below, this is what they are for.

==Material Emission Interactions==

Following are several examples of material emission interactions.

===Multiple Projectile Emission===

{{gamedata|title=Example [MATERIAL_EMISSION] interaction raws that fire three projectiles of the same material|
 <nowiki>[INTERACTION:MATERIAL_EMISSION_3]
	[I_SOURCE:CREATURE_ACTION]
	[I_TARGET:A:MATERIAL]
		[IT_MATERIAL:CONTEXT_MATERIAL]
	[I_TARGET:B:LOCATION]
		[IT_LOCATION:CONTEXT_LOCATION] <-- this is always the emitter for now
	[I_TARGET:C:LOCATION]
		[IT_LOCATION:CONTEXT_CREATURE_OR_LOCATION] <-- lets projectiles be aimed at specific creatures
		[IT_MANUAL_INPUT:target]
	[I_EFFECT:MATERIAL_EMISSION]
		[IE_TARGET:A]
		[IE_TARGET:B]
		[IE_TARGET:C]
		[IE_IMMEDIATE]
	[I_EFFECT:MATERIAL_EMISSION]
		[IE_TARGET:A]
		[IE_TARGET:B]
		[IE_TARGET:C]
		[IE_IMMEDIATE]
	[I_EFFECT:MATERIAL_EMISSION]
		[IE_TARGET:A]
		[IE_TARGET:B]
		[IE_TARGET:C]
		[IE_IMMEDIATE]</nowiki>
}}


By adding additional [I_EFFECT:MATERIAL_EMISSION] tags with their associated targets, you may stack additional projectiles.

===Predefined Material Emissions===

{{gamedata|title=Example [MATERIAL_EMISSION] interaction raws that use a predefined material|
 <nowiki>[INTERACTION:BASALT_EMISSION]
	[I_SOURCE:CREATURE_ACTION]
	[I_TARGET:A:MATERIAL]
		[IT_MATERIAL:MATERIAL:INORGANIC:BASALT:SOLID_GLOB] <-- the predefined material (INORGANIC), sub material (BASALT), and action type (SOLID_GLOB)
	[I_TARGET:B:LOCATION]
		[IT_LOCATION:CONTEXT_LOCATION]
	[I_TARGET:C:LOCATION]
		[IT_LOCATION:CONTEXT_CREATURE_OR_LOCATION]
		[IT_MANUAL_INPUT:target]
	[I_EFFECT:MATERIAL_EMISSION]
		[IE_TARGET:A]
		[IE_TARGET:B]
		[IE_TARGET:C]
		[IE_IMMEDIATE]</nowiki>
}}

If a material is listed in this format, the creature will not need a [CDI:MATERIAL] tag in their creature raws in order to use it. This allows projectile attacks to be gained through substance ingestion, other interactions, etc.

===Predefined Emissions of Different Types===

{{gamedata|title=Example [MATERIAL_EMISSION] interaction raws that use two predefined material types|
 <nowiki>[INTERACTION:BASALT_GRANITE_EMISSION]
	[I_SOURCE:CREATURE_ACTION]
	[I_TARGET:A:MATERIAL]
		[IT_MATERIAL:MATERIAL:INORGANIC:BASALT:SOLID_GLOB] <-- the predefined material (INORGANIC), sub material (BASALT), and action type (SOLID_GLOB)
	[I_TARGET:A1:MATERIAL]
		[IT_MATERIAL:MATERIAL:INORGANIC:GRANITE:LIQUID_GLOB] <-- the second predefined material (INORGANIC), sub material (GRANITE), and action type (LIQUID_GLOB)
	[I_TARGET:B:LOCATION]
		[IT_LOCATION:CONTEXT_LOCATION]
	[I_TARGET:C:LOCATION]
		[IT_LOCATION:CONTEXT_CREATURE_OR_LOCATION]
		[IT_MANUAL_INPUT:target]
	[I_EFFECT:MATERIAL_EMISSION]
		[IE_TARGET:A]
		[IE_TARGET:B]
		[IE_TARGET:C]
		[IE_IMMEDIATE]
	[I_EFFECT:MATERIAL_EMISSION]
		[IE_TARGET:A1]
		[IE_TARGET:B]
		[IE_TARGET:C]
		[IE_IMMEDIATE]</nowiki>
}}

This interaction fires both a solid glob of basalt and a liquid glob of granite magma.

===Material Emissions With Immunity===

{{gamedata|title=Example [MATERIAL_EMISSION] interaction raws that may only target creatures|
 <nowiki>[INTERACTION:CTARGET_BASALT_EMISSION] <-- The projectile itself
	[I_SOURCE:CREATURE_ACTION]
	[I_TARGET:A:MATERIAL]
		[IT_MATERIAL:MATERIAL:INORGANIC:BASALT:SOLID_GLOB] <-- the material tags used in the previous predefined material example.
	[I_TARGET:B:LOCATION]
		[IT_LOCATION:CONTEXT_LOCATION]
	[I_TARGET:C:CREATURE] <-- the may no longer be used on a location and must target a creature.
		[IT_CANNOT_HAVE_SYNDROME_CLASS:NO_EMISSION] <-- the syndrome class that makes targeting a creature with this interaction impossible.
		[IT_LOCATION:CONTEXT_CREATURE]
		[IT_MANUAL_INPUT:target]
	[I_EFFECT:MATERIAL_EMISSION]
		[IE_TARGET:A]
		[IE_TARGET:B]
		[IE_TARGET:C]
		[IE_IMMEDIATE]

 [INTERACTION:EMISSION_PROTECTION] <-- The ability that protects creatures from the above projectile
	[I_TARGET:A:CREATURE]
		[IT_LOCATION:CONTEXT_CREATURE]
		[IT_MANUAL_INPUT:target]
	[I_EFFECT:ADD_SYNDROME]
		[IE_TARGET:A]
		[IE_IMMEDIATE]
		[SYNDROME]
			[SYN_CLASS:NO_EMISSION]
			[SYN_NAME:protection from projectiles]
			[CE_FLASH_TILE:TILE:'O':7:0:1:FREQUENCY:2000:1000:START:0:END:2:ABRUPT:DWF_STRETCH:144]
</nowiki>
}}

Material emissions used in this format are affected by [IT_CANNOT_HAVE_SYNDROME_CLASS:X] tags (given above as the custom tag NO_EMISSION). This allows a modder to create immunity syndromes, disallowing a creature using the emission interaction from targeting the creature with immunity.

==Multi-Stage Interactions==
These are more elaborate groups of interactions that allow you to create complex behaviors by using interactions to enable or disable other interactions.

===Timed Self-Destruct (or other powerful ability) with Override Ability===

This will allow the user to explode after spending a certain amount of time in combat.  A few ticks before exploding, it will flash with a "!" as a warning.
You can also replace the explosion with any other powerful ability that you want it to use only after a countdown.
It also comes with a syndrome that will disable the explosion.
This is intended to be used by non-playable units, like animals or zombies.
